Anyone know any workarounds for this?

pallid mesa Feb 14, 2018, 10:09 AM

#

Yep, just on your RPC Multicast have a boolean input bSkipOwner and on remote you need to check if(!(IsLocallyControlled() || bSkipOwner)) {DoStuffSkippingOwner()}

#

So instead using variable replication condition, you just do it yourself

ripe raptor Feb 14, 2018, 10:26 AM

#

Welp, it's not BP specific, a TArray<TSubClassOf<SomeUObjectClass>> in code isn't initially replicating either.

twin juniper Feb 14, 2018, 12:51 PM

#

i want to make a game online MP. giving the other person the packaged game and then he starts t he game immediately connecting with my server.

#

i just want to share the pawn character

ripe raptor Feb 14, 2018, 12:51 PM

#

Where can I override the default "destroy the pawn if the client disconnects" behavior?

bitter oriole Feb 14, 2018, 12:51 PM

#

@twin juniper What's your question ?

twin juniper Feb 14, 2018, 12:52 PM

#

😦 replicating the pawn character. how?

#

i don't want to watch 20 videos of networking

#

can't find a single youtube tutorial max. 20 minutes

bitter oriole Feb 14, 2018, 12:53 PM

#

Don't expect anything on a network to not take hours of work

twin juniper Feb 14, 2018, 12:53 PM

#

as i said, i don't want to create warcraft!

#

just sharing data of pawn char.

#

and auto. connecting when starting .exe

bitter oriole Feb 14, 2018, 12:54 PM

#

It's still going to take time and effort

twin juniper Feb 14, 2018, 12:54 PM

#

omg :/

bitter oriole Feb 14, 2018, 12:54 PM

#

People here can help but you can't start out saying you only have 20 minutes

twin juniper Feb 14, 2018, 12:54 PM

#

it doesn't take more than 20 minutes. that's the joke

bitter oriole Feb 14, 2018, 12:55 PM

#

There is no single tutorial because multiplayer is huge, it covers every aspect of your game. You might think you just want to share a pawn but you still said "server" (so you need a dedicated server), and you said "auto connect" (so you need to work on a way to connect to something)

#

It's the simplest case but it's still far from trivial

twin juniper Feb 14, 2018, 12:56 PM

#

my pc as server

#

the integrated UE thing

bitter oriole Feb 14, 2018, 12:56 PM

#

That makes it harder

#

Now you want matchmaking, too

twin juniper Feb 14, 2018, 12:57 PM

#

o.o

#

not matchmaking

bitter oriole Feb 14, 2018, 12:57 PM

#

Well, you need a way for your friends to know which IP address to connect to

#

That's what matchmaking does

#

Unless you are making a game specifically for you and your friend only and you have a static IP address that you hardcode into the game

twin juniper Feb 14, 2018, 12:58 PM

#

i have only one ip adress.

#

static ya

#

germany is full with static ip's

bitter oriole Feb 14, 2018, 12:59 PM

#

And this game is only for the two of you ?

twin juniper Feb 14, 2018, 12:59 PM

#

ya

#

i could try lan with tunngle but...

bitter oriole Feb 14, 2018, 12:59 PM

#

Then you have one less thing to worry about

twin juniper Feb 14, 2018, 1:00 PM

#

or just connect 4 other players with my static ip. (for the future)

bitter oriole Feb 14, 2018, 1:00 PM

#

So what have you tried for now ?

twin juniper Feb 14, 2018, 1:00 PM

#

nothing.

bitter oriole Feb 14, 2018, 1:00 PM

#

You don't have a game ?

twin juniper Feb 14, 2018, 1:01 PM

#

i have

bitter oriole Feb 14, 2018, 1:01 PM

#

So have you tried starting it with two players locally to see what happens ?

twin juniper Feb 14, 2018, 1:01 PM

#

no?

bitter oriole Feb 14, 2018, 1:01 PM

#

Then do that 😉

#

There are a few introduction videos here : https://www.unrealengine.com/en-US/blog/blueprint-networking-tutorials

Unreal Engine

Blueprint Networking Tutorials in Unreal Engine 4

A previous blog post offered a crash course in blueprint networking, but now we’re back with a thrilling six-part mini-series on creating blueprint content that works in a networked game!

#

2 hours overall, with basic functionality in 30minutes

#

I suggest you start here

twin juniper Feb 14, 2018, 1:03 PM

#

i saw this one few months ago.

#

wasn't that much of a help.

#

just showed examples.

#

when i start 2 players now, one player starts with a fixed camera. no character

bitter oriole Feb 14, 2018, 1:04 PM

#

Examples are what you're going to get

#

People don't do tutorials specifically for your own game

#

Watch, understand, and adapt

twin juniper Feb 14, 2018, 1:04 PM

#

sigh okey

bitter oriole Feb 14, 2018, 1:05 PM

#

I mean, adding multiplayer to my game prototype took me a week, and I've done multiplayer games before

#

For most games you're going to work on mutliplayer from day 1 to the last day you work on it

#

It's not just a game feature, it defines entirely how your game works

#

You really shouldn't expect it to just work, even with UE4

twin juniper Feb 14, 2018, 1:08 PM

#

😦

#

@bitter oriole make a video what you learned and upload it on youtube ;D

#

... wtf

#

@twin juniper

#

opps i thought this was #lounge

#

i can't control the second player when setting field to 2 in number of players @bitter oriole

zenith yarrow Feb 14, 2018, 2:06 PM

#

@ripe raptor override PawnLeavingGame() in your controller, do not call super, simply call UnPosses()...

#

that should do it, you may have to test it out though...

ripe raptor Feb 14, 2018, 2:09 PM

#

Yeah I figured it out in the meantime, thanks

bitter oriole Feb 14, 2018, 2:14 PM

#

@twin juniper Take it slow and test everything super carefully

#

I log stuff on screen myself to check what happens

#

GEngine->AddOnScreenDebugMessage(-1, 10.f, FColor::Red, TEXT("Something happened"));

#

Make sure your input bindings work, make sure the output log doesn't say anything strange

worn nymph Feb 14, 2018, 2:16 PM

#

why i changed my name to this i print string on everything lol

bitter oriole Feb 14, 2018, 2:17 PM

#

Your dev chain should be to test locally with one player, then move on to 2p in editor, then work with two computers locally, and then test on network

#

Take it slow

#

Networking is hard

worn nymph Feb 14, 2018, 2:17 PM

#

programming is 10% making a sytem 90% debugging it

bitter oriole Feb 14, 2018, 2:20 PM

#

Multiplayer programming is 10% making it work for one player, 70% making it work for two players locally, and 20% making it work in the real world, in my humble experience

#

At least with UE4+Steam, since they make the real-world part way easier

twin juniper Feb 14, 2018, 2:34 PM

#

localy with others pcs isn't possible

#

have only one powerful pc

#

one old macbook

bitter oriole Feb 14, 2018, 2:35 PM

#

Too bad, it's very helpful

#

But at least be sure to work in stages

twin juniper Feb 14, 2018, 2:37 PM

#

how can i log the 2nd player?

#

it's nothing i have coded, so. can't work

bitter oriole Feb 14, 2018, 2:38 PM

#

Log it just like you log the first player

#

If you want to be sure about how it works, don't work with the editor

#

Launch the game by rightclicking the project file and clicking "launch", twice

#

Launch one as a listen server and do "open localhost" on the other

twin juniper Feb 14, 2018, 2:40 PM

#

how do I do all of these things? 😄

#

i should open 2 unreal engine editors?

#

right click what project file? oO

bitter oriole Feb 14, 2018, 2:41 PM

#

Your .uproject file.

twin juniper Feb 14, 2018, 2:41 PM

#

i dont even log the first player....

bitter oriole Feb 14, 2018, 2:42 PM

#

Multiplayer requires

experience with making games with UE4
experience with command lines, building code, hosting servers
patience and time

#

Like I said earlier, it's hard

twin juniper Feb 14, 2018, 2:43 PM

#

in a later stage it does require that, but not in the beginning?

bitter oriole Feb 14, 2018, 2:43 PM

#

Multiplayer is hard from the beginning to the end

#

Because you can't do only half of it

#

Not to mention that you're going to need / want to be writing code at some point

#

Make sure you fully understand how everything you currently have works, to start with. Don't use marketplace Blueprints or funny plugins, if you have some

twin juniper Feb 14, 2018, 2:47 PM

#

i am sure you don't understand me. can't be so hard regarding other youtubers .)

bitter oriole Feb 14, 2018, 2:48 PM

#

Well, I'm a C++ programmer on my 2nd MP game, third game overall, and I find it hard 😃

#

I'm not the brightest person though

mild hull Feb 14, 2018, 2:49 PM

#

its not hard to get something simple going but its better to build your game while knowing the limitations you have to avoid than to run into them and than replan

twin juniper Feb 14, 2018, 2:50 PM

#

i am just testing. i dont want to build anything upon that

jolly siren Feb 14, 2018, 2:50 PM

#

Latency is what makes everything fun 🙂

bitter oriole Feb 14, 2018, 2:50 PM

#

My first game was a multiplayer one, a simple multiplayer shooter. Well, it took me a year and a half, and I never really got it working well

twin juniper Feb 14, 2018, 2:50 PM

#

@bitter oriole in the past, when i read you, i find that you do stuff very complex 😄 and you explain things very complicated.. sooo 😛

bitter oriole Feb 14, 2018, 2:51 PM

#

So @twin juniper back to how to get it to work : you know command lines ?

twin juniper Feb 14, 2018, 2:51 PM

#

not in german

#

~

bitter oriole Feb 14, 2018, 2:51 PM

#

I mean, the "cmd" tool in Windows

twin juniper Feb 14, 2018, 2:51 PM

#

oh ya

bitter oriole Feb 14, 2018, 2:52 PM

#

Right now you're playing from editor, but in the editor, multiplayer is kind of strange

#

it works differently, doesn't have all features, it's just weird

twin juniper Feb 14, 2018, 2:52 PM

#

you mean output log in UE is important?

#

when 2nd player doesnt move etc?

#

i am reading it now

#

LogSpawn: Warning: SpawnActor failed because of collision at the spawn location [X=94.991 Y=1970.000 Z=2502.200] for [PhysicsBallBP_C]

bitter oriole Feb 14, 2018, 2:53 PM

#

Well, that's a good start. No second player because, probably, you have only one player start

twin juniper Feb 14, 2018, 2:53 PM

#

i tried with 2 player starts..

bitter oriole Feb 14, 2018, 2:54 PM

#

See, this is part of why in-editor sucks for multiplayer

#

Your two players are spawning at the same time

#

They might be competing for the spawn point

twin juniper Feb 14, 2018, 2:54 PM

#

o.ö

bitter oriole Feb 14, 2018, 2:55 PM

#

You'll need to handle that by changing the spawn logic, but that's for later

#

For now you can work outside editor, start one game in listen server, move away from spawn, start another game, connect to server, and it will spawn

#

To start without editor, go to your project root directory, right click the blue .uproject file, hit launch.

#

Then open the console (²), and you can start a listen server, or connect to one

twin juniper Feb 14, 2018, 2:56 PM

#

oh its working now... i gave spawns more space to breath... cough

#

it didnt even say bad size

#

ah

bitter oriole Feb 14, 2018, 2:58 PM

#

Well, you'll need to work with the standalone (no-editor) modes at some point anyway

#

So it's okay

twin juniper Feb 14, 2018, 2:59 PM

#

isnt standalone the one which makes the pc laggy?

#

😡

#

start one game in listen server.. oh .... so what is that?

bitter oriole Feb 14, 2018, 3:00 PM

#

Listen server = server where you also play the game

#

As opposed to dedicated server (people connect to it, but it doesn't show anything or has inputs, and is usually in a datacenter without a screen or keyboard)

twin juniper Feb 14, 2018, 3:02 PM

#

standalone is now loading

#

² is console? XD

#

ok i press ² but nothing happens

#

again, i am german.

bitter oriole Feb 14, 2018, 3:03 PM

#

Might look at the editor options to check the console key

mild hull Feb 14, 2018, 3:03 PM

#

below Esc if its default key

twin juniper Feb 14, 2018, 3:05 PM

bitter oriole Feb 14, 2018, 3:10 PM

Does it work when you play in-editor ?

twin juniper Feb 14, 2018, 3:11 PM

#

works as a key. in-editor ya.

bitter oriole Feb 14, 2018, 3:12 PM

#

So you can open the console ?

twin juniper Feb 14, 2018, 3:12 PM

#

in the editor ya

#

^^

mild hull Feb 14, 2018, 3:14 PM

#

while opening console is important for starting listen server/ client i would create bat files
listen.bat
"EnginePath\Engine\Binaries\Win64\UE4Editor.exe" "ProjectPath\ProjectName.uproject" /Game/PathInContentFolder/MapName?listen -game -log
client.bat
"EnginePath\Engine\Binaries\Win64\UE4Editor.exe" "ProjectPath\ProjectName.uproject" 127.0.0.1 -game - log

Is there a way of checking if a variable is updated across the network without displaying it on the UI (e.g. Overhead UI)

tall grove Feb 14, 2018, 9:17 PM

#

someone can recommend me a book/website/video.... to learn how to manage AI Multiplayer? Things like strategies , algorithms to select target .....

winged badger Feb 14, 2018, 10:17 PM

#

there are some resources pinned on this channel

#

as for AI multiplayer, the AIControllers do not exist on clients

#

so its not really a multiplayer issue

#

as for AI, the example docs on epic site should get you started (Bahviour Trees and Envirnonment Querry System)

tawny parcel Feb 14, 2018, 11:55 PM

Anyone know why dedicated server log files are not adding the .log extention when created?

carmine frost Feb 15, 2018, 1:57 AM

#

are you overriding the log filename via the command-line? 😃

twin juniper Feb 15, 2018, 3:49 AM

#

alright guys i finally figured out how to use seamless travel

#

but for some reason

#

it keeps loading my main menu

#

it just refreshes the main menu

#

when i write in the IP

#

PC->ClientTravel(IP, ETravelType::TRAVEL_Relative, true);

#

is there something wrong here?

#

the ip address is on an external serverr

Damn replication/server/client stuff. While I got most of it working, it's really killing the fun (came back after a 4 day break of no interest).

limber bluff Feb 15, 2018, 4:59 AM

#

quick question; is it possible to hav mobile/vr players play with people playing on pc?

thin stratus Feb 15, 2018, 9:10 AM

#

Technically yes

#

As long as you find a way to connect them

#

Aka your own backend

#

In LAN it should work right away

#

Same for direct ip connection

#

@twin juniper Are you using Seamless Travel from MainMenu to Server?

#

@limber bluff

#

See a bit further up. Didn't see how old the message was so guess i ping you

#

@opaque seal Yeah, singleplayer gives you a lot more freedom as not wonder when what is replicated or connected. :P

ripe raptor Feb 15, 2018, 11:37 AM

#

If I do a ServerTravel, the clients will follow, yes?

#

Nevermind, stupid question

thin stratus Feb 15, 2018, 12:16 PM

#

Anyone did LevelStreaming with Multiplayer yet?

#

I'm trying to make sure that doors on a client won't open until the level is loaded.
Level Loading is replicated as far as I understood and I make sure to not call the ClientRPC until the "Loading Complete" executes.

#

However is that also making sure that the level loaded on the client?

#

@mystic pilot Do you have a minute for me?

#

Actually, I think you did something a bit different. You wanted to load levels that aren't in the levels tab

#

Nvm then. Hm

#

My main problem is, is the loading replicated or not and if not, does the Server need to load the level too or would it be enough to load it on the client (collision tracing etc would fail without server version)

twin juniper Feb 15, 2018, 12:51 PM

#

@thin stratus yeah

#

ClientTravel(FString("108.22.33.44", ETravelMode::Relative, true);

thin stratus Feb 15, 2018, 12:51 PM

#

So my testing for now gives: Load Level on Server -> Loads on everyone

#

I tested that on 2 Instances on the same PC. Will still have to check it on a package game on two different PCs.

twin juniper Feb 15, 2018, 12:52 PM

#

Collision is server sided

#

load all of your levels on the server

#

and let clients stream them in and out

thin stratus Feb 15, 2018, 12:52 PM

#

Loading a Level on the Server loads the level on the clients

#

At least in what I just debugged

#

Which is not bad, it's fine, as long as this is actually working when I package next time

limber bluff Feb 15, 2018, 2:09 PM

#

@thin stratus thank you, sorry it took so long to notice

ripe raptor Feb 15, 2018, 2:12 PM

#

uh-oh

#

"reliable buffer overflow"

winged badger Feb 15, 2018, 2:17 PM

#

might had multicasted one too many times there

twin juniper Feb 15, 2018, 2:23 PM

#

@thin stratus did u figure it out?

thin stratus Feb 15, 2018, 2:46 PM

#

@ripe raptor Don't put reliable on everything :P specially tick

#

@twin juniper Not more than I wrote

ripe raptor Feb 15, 2018, 2:46 PM

#

This isn't Tick, it's a character's melee attack... the fast ones 😦

twin juniper Feb 15, 2018, 2:46 PM

#

@thin stratus you have to enable "Client Sided Level Streaming" in AWorldSettings

#

It's a simple boolean toggle

thin stratus Feb 15, 2018, 2:48 PM

#

What does that exactly?

#

@twin juniper

twin juniper Feb 15, 2018, 2:51 PM

#

@thin stratus It makes it so that you can load a level on the client side

thin stratus Feb 15, 2018, 2:52 PM

#

So only on the Client?

twin juniper Feb 15, 2018, 2:52 PM

#

https://i.imgur.com/rHpa1L7.png

Imgur

#

Yeah

thin stratus Feb 15, 2018, 2:52 PM

#

But I would still need to also load it on the Server to make sure that the client has no replication issues

#

Ah

#

Server has them all loaded

#

Is that default then or do I need to do something for that

twin juniper Feb 15, 2018, 2:52 PM

#

It is default if youn are using world composition

#

but you can set it up however you want

thin stratus Feb 15, 2018, 2:53 PM

#

So:

Server-Side:

Server and Clients share loading
Maps get loaded by Server
Replicated to Clients
Clients don't call the load function manually

Client-Side

Server always has all Maps loaded
Clients can locally decide if they want to load a map

#

@twin juniper

#

Just wanting to make sure I get exactly how this works

twin juniper Feb 15, 2018, 2:56 PM

#

Using world composition? Or Manually?

If manually, you could load the map in gamemode begin play function if(HasAuthority()) {} and then, when a client connects they can just call Load Stream Level whenever they need to load a new section, or Unload Level when the yneed to unload.

#

But I do not believe maps loaded on the server get lreplicated to clients, only the collision will be replicated I believe (so you dont fall through the world)

#

Clients should be able to call Load Level manually

#

Does that make sense?

#

@thin stratus

#

Server:

Holds all levels, repllicates collison to clients
Maps loaded by server

Client:
Clients can call load on a specific section or use a level streaming volume
Clients can also unload a map as well

tall grove Feb 15, 2018, 3:04 PM

#

@twin juniper do you know if this is posible with load level instance instead level streaming?

#

this = Server:

Holds all levels, repllicates collison to clients
Maps loaded by server

Client:
Clients can call load on a specific section or use a level streaming volume
Clients can also unload a map as well

twin juniper Feb 15, 2018, 3:04 PM

#

I believe it's possible for all of the loading functions

#

Though I have not tested it

#

So I cannot say for sure.

#

But what I do know is that you are able to load and unload levels on the client side

tall grove Feb 15, 2018, 3:05 PM

#

When i unload a map from server , client unloads too

#

i will test again cause i dont remember rigth now , but i think client cant load map without load on server

#

maybe loading map wiyhout rendering....

#

i will test all of this next day

twin juniper Feb 15, 2018, 3:08 PM

#

have you enabled

#

the client sided level streaming?

tall grove Feb 15, 2018, 3:12 PM

#

no , cause is not level streaming i use load level instance node...

thin stratus Feb 15, 2018, 3:13 PM

#

Okay thing is

tall grove Feb 15, 2018, 3:13 PM

#

i dont use volumes , should i use?

thin stratus Feb 15, 2018, 3:13 PM

#

In the Server-Side thing

#

It def loads the Level for Clients if LoadLevel is called on Server

#

(Streaming, not instance!)

#

I have the Persistent level and 3 sublevels

#

Server Loads Sublevel -> all Clients load it

#

That's not ideal, cause the other clients don't need the level to be loaded

#

When you enable Client-Side, it would load only for the local Client

#

But for moving, trace checks etc, it still needs to be loaded on the Server

summer nova Feb 15, 2018, 3:14 PM

#

@thin stratus there is something that im doing right now about MP, that im not very sure about

thin stratus Feb 15, 2018, 3:14 PM

#

Now, the Server shouldn't load ALL levels, even though no one needs them

#

Does he?

summer nova Feb 15, 2018, 3:15 PM

#

i have an enemy that can perform CombatActions (basically an anim with some extra logic). Right now its a multicast to sync it

thin stratus Feb 15, 2018, 3:15 PM

#

Like, if all players are in the persistent level

#

Why would I load all maps on the Server

summer nova Feb 15, 2018, 3:15 PM

#

but im thinking, could it be a repnotify?

thin stratus Feb 15, 2018, 3:15 PM

#

@twin juniper

#

So either the Server has them all loaded already in Client-Side mode and I just have to deal with that

#

Or Loading on client will load on Server

instead of doing a reliable multicast of "PlayCombatAnim()", it sets the replicated "CurrentCombatAnim" variable to something

thin stratus Feb 15, 2018, 3:15 PM

#

Or Server has a way of only loading collision

summer nova Feb 15, 2018, 3:15 PM

#

and it repnotifies

thin stratus Feb 15, 2018, 3:16 PM

#

Or I need to load on client and on server

#

@summer nova technically a RepNotify isn't really needed here

#

The RPC should be enough

#

The Anim is Fire and Forget

twin juniper Feb 15, 2018, 3:16 PM

#

Oh wow

thin stratus Feb 15, 2018, 3:16 PM

#

If someone else comes in after it was fired, they don't need to get that state update

twin juniper Feb 15, 2018, 3:16 PM

#

That doesn't sound normal.

summer nova Feb 15, 2018, 3:17 PM

#

do multicast get called if you dont have relevancy?

#

RELIABLE multicast

thin stratus Feb 15, 2018, 3:17 PM

#

Shouldn't

#

If you aren't in range, you don't get the call

summer nova Feb 15, 2018, 3:17 PM

#

good enough then

tall grove Feb 15, 2018, 3:17 PM

#

RepNotify only if you want let clients reconnect if they lost conexion and not for sync anim

summer nova Feb 15, 2018, 3:17 PM

#

thanks, ill just use multicast

thin stratus Feb 15, 2018, 3:17 PM

#

RepNotifies is always good to sync up late joiners and people coming into range

#

Like a Chest opening

#

Shouldn't be RPC

summer nova Feb 15, 2018, 3:18 PM

#

another thing. What is the overhead of having replicated components

thin stratus Feb 15, 2018, 3:18 PM

#

Cause if someone comes in later, the RPC won't call anymore

#

And the chest stays closed

summer nova Feb 15, 2018, 3:18 PM

#

just so i can do an RPC on it

#

not really replicating any variable

thin stratus Feb 15, 2018, 3:18 PM

#

Not much I assume

#

Check the component in c++

#

And see if they replicate something

#

If not, then no real overhead I would say

#

@twin juniper I'll play around with the Client-Side stuff

#

After all I can print if a level is loaded or not

#

So I'll just see what happens if I tick the bool :D

twin juniper Feb 15, 2018, 3:19 PM

#

Cedric

thin stratus Feb 15, 2018, 3:19 PM

#

Thanks for the info though, didn't know about the bool

twin juniper Feb 15, 2018, 3:19 PM

#

I really don't think it should be loading on clients if you load on the server

#

Otherwise, it would mean that the "bUseClientSidedLevelStreaming" would not be working as intended

#

Unless I am misunderstanding something?

thin stratus Feb 15, 2018, 3:19 PM

#

I'm not using that atm

#

As said, I currently use Server-Side

twin juniper Feb 15, 2018, 3:20 PM

#

Oh

thin stratus Feb 15, 2018, 3:20 PM

#

Server loads -> Everyone loads

#

I didn't know about the boolean

twin juniper Feb 15, 2018, 3:20 PM

#

Oh okay

thin stratus Feb 15, 2018, 3:20 PM

#

Now I just want to know what I have to do with the server in the Client-Side approach

winged badger Feb 15, 2018, 3:20 PM

#

as far as i know server needs to set the levels visible to client as well at some point

twin juniper Feb 15, 2018, 3:20 PM

#

@thin stratus if you load all maps on the server though

#

Does it work?

#

With that boolean enabled

thin stratus Feb 15, 2018, 3:20 PM

#

Idk that's my question

twin juniper Feb 15, 2018, 3:21 PM

#

I have tested it before when I wasn't using world composition

#

and it was working

thin stratus Feb 15, 2018, 3:21 PM

#

I mean, Client-Side approach
Local Client Loads -> Only Local Client gets map

twin juniper Feb 15, 2018, 3:21 PM

#

back in 4.16 lol

thin stratus Feb 15, 2018, 3:21 PM

#

But do I have to do something for hte Server

twin juniper Feb 15, 2018, 3:21 PM

#

mhm

#

So here's how it works though

#

Collision is always server authoritative

#

So if you load that map on the client, the client walks i nto it, they will fall through the world if the server hasnt loaded that map as well

#

Make sense?

thin stratus Feb 15, 2018, 3:22 PM

#

Lemme give you small portion of info then

#

It's a VR Project where you TP through the loaded levels

#

So no Physics/Gravity/Falling

#

Only thing that could be is that there is an actor in the scene

#

That needs to be tracable by Client and Server

#

To replicate

#

So I 100% need to be sure that if I have Server, ClientA and ClientB, that if either of the two Clients load the level, it is loaded on the server too

twin juniper Feb 15, 2018, 3:23 PM

#

Yeah

#

Makes sense.

thin stratus Feb 15, 2018, 3:23 PM

#

And the question persists -> Do I have to manually load on the Server too

#

In Client-Side

twin juniper Feb 15, 2018, 3:23 PM

#

Yeah I believe so

#

I know that even with world composition, when I load a server I get this log

#

one sec

thin stratus Feb 15, 2018, 3:24 PM

#

I'll probably just have to print "IsLevelLoaded"

#

On Server and Clients

#

And see what is true and what not

twin juniper Feb 15, 2018, 3:24 PM

#

I really wish that unreal had an "IsAnyLevelLoading" function lol

thin stratus Feb 15, 2018, 3:24 PM

#

Well I currently only have 3 levels

#

So I have the "LoadLevel->IsLevelLoaded" or what ever it is 3 times

#

(To debug)

twin juniper Feb 15, 2018, 3:25 PM

#

yea

winged badger Feb 15, 2018, 3:25 PM

#

if you're loading them manually, you can just make one @twin juniper

thin stratus Feb 15, 2018, 3:25 PM

#

Well yeah, add them to an array when loading and remove when unloading

winged badger Feb 15, 2018, 3:25 PM

#

set bIsAnyLevelLoading to true when you start a load and false it on completed

thin stratus Feb 15, 2018, 3:25 PM

#

Oh, loading

#

In terms of "currently loading"

twin juniper Feb 15, 2018, 3:26 PM

#

@winged badger true

thin stratus Feb 15, 2018, 3:26 PM

#

Yeah we are having an Elevator that is closed when loading

#

And only opens the doors when loading is finished

twin juniper Feb 15, 2018, 3:26 PM

#

So here's the thing though

#

Why not load all levels on the server just to be 100% safe?
If you cannot, just load on client, then call the same on the server

winged badger Feb 15, 2018, 3:27 PM

#

there is one pitfall with AlwaysLoaded

#

https://answers.unrealengine.com/questions/342708/replication-issue-of-actors-placed-in-always-loade.html

twin juniper Feb 15, 2018, 3:27 PM

#

Not talking about always loaded lol

thin stratus Feb 15, 2018, 3:27 PM

#

The whole idea of LevelStreaming in my case is performance. We are talking about ArcViz Levels which are more and more to come.

twin juniper Feb 15, 2018, 3:28 PM

#

you can set a level to be loaded via "Blueprint" (really just means, as defined by any code, blueprint,C++...etc)

thin stratus Feb 15, 2018, 3:28 PM

#

Currently I call load on Server and afterwards tell the Client to open the Elevator doors. I have no problem just placing another load for the client before opening the doors

#

So I would route for 2) anyway

twin juniper Feb 15, 2018, 3:28 PM

#

You have to realize though that the server doesn't render graphics

#

So what would be the performance loss on the server?

thin stratus Feb 15, 2018, 3:28 PM

#

(ListenServer)

#

So there is loss :D

twin juniper Feb 15, 2018, 3:29 PM

#

oh

#

Okay that makes sense then

#

I hate listen servers lol

#

AHH

#

Honestly, though, I would simply just mess around with the client sided level streaming

#

I can't really say sadly.

thin stratus Feb 15, 2018, 3:30 PM

#

All fine. The discussion helped a lot

#

Gonna implement that next time I work on the project

#

Cheers!

Hello, do you have good tutorial to know how to start replication for dedicated server and how handle MMO?
what engine is the most optimised, and easy to use for small team? UE4? or anything else?

thin stratus Feb 15, 2018, 6:05 PM

#

UE4 is pretty optimized for small teams and big teams (GameJams show that)

#

There are no tutorials on Replication for Dedicated Servers. General replication applies to this.

#

UE4 can't handle MMOs by default.

#

Latest 4.19 changes will make it possible to have multiple players on the same server (100 people battle royal)

#

But I don't think the default UE4 servers can handle a few thousand people

#

So if at all, you'd need to work with small groups of players and move them around between servers

#

And then it might be easier to setup your own backend

#

instead of ue4 servers

#

@thorn arrow

#

But this is just my 2cents

#

Can totally be that someone already managed to get MMO working with pre 4.19 and more than 100 players

#

Probably with engine changes or own code though

thorn arrow Feb 15, 2018, 6:11 PM

#

Yhea, ok i'm looking for custom engine, like panda3D, but if another framework or engine is made for make easier the creation of mmo, that would be great

thin stratus Feb 15, 2018, 6:12 PM

#

There are a few systems that integrate into any sort of engine

#

So you might actually be better with chosing the engine NOT on the base of "mmo or not"

#

And rather check if you can find a thirdparty service

#

that you can integrate into the engine

#

Obv if there is an engine for MMOs and you are fine with what they offer, then take it

graceful lynx Feb 15, 2018, 6:21 PM

#

I agree with @thin stratus he's 100% right. If you're chosing an engine for an MMO, look at it's adaptability to put in your own third party networking that allows you the greatest control over your packets. The engine will likely be handling local physics collisions, as well as rendering etc. But something like Smartfox Server 2x, or better yet something like RakNet is highly recommended but you'll need to modify it to a instanced based room MMO system. With a larger overworld chat system and a decently fast DB handling. You'll also need to figure out scaling deployments so that you can scale out laterally rather than horizontally.

#

It's all quite do-able at this point, but expect a ton of challenges. I got help from some heavyweights when I was starting on mine

#

@thorn arrow expect to need to modify even the third party software like RakNet as it's behind on security updates and has at least one memory leak I'm pretty sure

#

We chose UE4 for our MMO because having the ability to peer into the source made us not hate life.

#

@thin stratus Do you happen to know if there's any notes on the IHTTP module? I've been having some significant issues with it on only OSX, it seems like it's doing some weird shit and automatically redicting the response and clearing the redirect-response header and therefore making me lose that information (which I need for a new auth setup to be CAS compliant)

#

I haven't found anything on it on google, unreal's answer board, or in source that's relatively useful

thin stratus Feb 15, 2018, 6:30 PM

#

Haven't used it on OSX

#

Nothing that I know about for Windows

graceful lynx Feb 15, 2018, 6:32 PM

#

alright :/ I've got windows working at the moment, so it's really OSX that's the issue

#

but I guess I'll just dig through source more and try to figure it out haha

twin juniper Feb 15, 2018, 6:53 PM

#

i think ue4 networking

#

cant do mmo lol

graceful lynx Feb 15, 2018, 6:53 PM

#

It can't lol, you need to use a third party library

#

RakNet works out pretty well in my experience if you modify it quite a bit

twin juniper Feb 15, 2018, 6:54 PM

#

im not sure why though

#

is it literally just

#

bandwidth?

#

or is it an engine issue

#

like ticking too much, (this also could be using too much bandwidth if we are sending stuff to often)

#

lol

graceful lynx Feb 15, 2018, 6:57 PM

#

There's a few reasons why it doesn't work out too well. The first is how Unreal's server needs an unreal server build, which is heavier generally than a third party server library. The second, yes is bandwidth, Unreal is an FPS engine slightly. It does very well for high frequency check in games that need frequent check ins. The third major thing is that it's not really optimized to work too well with giant worlds while networked, and I don't believe it has a system to LOD in and out players into different tick serialization groups depending on location within a larger map. On top of this it would take quite abit of work to add that in. When all's said and done, you can get something done in a much easier way by using a third party networking library for this stuff

#

that said, there are always exceptions to rules, and if you were to dig into unreal source and begin to tweak it, you may be able to get it to do what you want.

#

I'd really recommend that you do some reading first on what classic MMO Architecture looks like before you chose and engine, I highly recommend this book by the IT Hare. http://ithare.com/contents-of-development-and-deployment-of-massively-multiplayer-games-from-social-games-to-mmofps-with-stock-exchanges-in-between/

IT Hare on Soft.ware

"No Bugs" Hare

Contents of “Development and Deployment of Multiplayer Online Games: from social games to MMOFPS, with stock exchanges in between” - IT Hare on Soft.ware

Table of Contents of the upcoming book on various aspects of game development and deployment, from business requirements to bot fighting

#

this book is super old but good in some of it's content: https://www.amazon.com/Massively-Multiplayer-Game-Development-v/dp/1584503904/ref=sr_1_2?s=books&ie=UTF8&qid=1518721463&sr=1-2&keywords=Massively+Multiplayer+Game+Development I really recommend looking at the "Big Brother Server" chapter

#

Keep in mind, that the amazon book I mentioned above, is 13 years old... So do not take it as gospel, you should definitely run it through a lens of "this is what used to be done". What's done now is far more distributed.

#

On another note, if anyone know what the heck is going on with the http module on OSX, please let me know, because I've been staring at the objective c wrapper for the http handling for applehttp so much for any clue of why it's clearing my redirection packet that contains the header content I need that my eyes are getting blurry.

dull tapir Feb 15, 2018, 7:35 PM

soo... trying to get into multiplayer once again and I still can't really get my head around it the whole replication thing. Dunno why I struggle so much with it. I created a game mode and a player controller. Inside the game mode I am using OnPostLogin to call an event inside the player controller, which I have set to Run on owning Client. Right now the event just prints a string, but when I test there is no string being printed? What am I doing wrong? 😦 I made sure both actors have Replicates set to true and also made sure it's using the correct game mode in my level and that I've set the correct player controller inside the game mode.

winged badger Feb 15, 2018, 7:56 PM

#

@stark dome its valid as soon as its construction script is done

#

you can put your own

stark dome Feb 15, 2018, 7:57 PM

@winged badger theres nothing in engine for it?

takes a while for it be valid on clients

damn, multiplayer channel

stark dome Feb 15, 2018, 7:58 PM

#

yeah other variables are sometimes replicated before it which is a pita

winged badger Feb 15, 2018, 7:58 PM

#

its valid when it starts replicating MatchState

#

if you're using GameMode/StateBase

#

altho, its cunstruction script is run on client as well, after its replicated

#

if you fire the event from the very end of it, it should be valid at that point

#

or from PostInitializeComponent() override, which comes right after

Is there any decent guides on making backend servers? Dedicated servers that start/stop when new sessions are formed. A cloud/master server kind of setup, where you start to manage things like persistant statistics, and not having player-hosted servers.

#

Garden wall.

livid ruin Feb 15, 2018, 10:41 PM

#

@dull jasper we have stopped using it now. But we are unsure as to why the non-host client cannot find the host game.

thin stratus Feb 15, 2018, 10:41 PM

#

@opaque seal One way is using cloudhosting like gamelift

#

And gamesparks for the stats and matchmaking

opaque seal Feb 15, 2018, 10:42 PM

#

Yeah but I mean the software side of things.

#

Or are they plugins?

worthy wasp Feb 15, 2018, 10:42 PM

#

@opaque seal - coming from a bachelors in computer networking and a 10 year higher-end sales & technical setup/support position for IT... i'm going to say that all of that stuff is pretty advanced. if you're not an above intermediate level of programming, and understand more than just code syntax - but server technologies, TCP/IP stack + above all else - communication standards for FullStack development - then you're in over your head already.

I dont even pretend to know much about the DEVELOPMENT side of backend servers, but i do understand their functionality and communications methods. To be honest - what Cedric just said is the best option - using a Backend as a Service (BAAS) cloud solution. Photon, Amazon Web Services, Gamesparks, SpatialOS

you can ge tby pretty far with PHP & scripting - but when you come to more robust & heavier traffic solutions - look up Mike Allar's stuff on youtube

thin stratus Feb 15, 2018, 10:44 PM

Most things are basic server and database tutorials

You have to utilize these to code your backend

thin stratus Feb 15, 2018, 10:47 PM

#

Eeehm

#

Last time i used that i didn't have any problems like that

#

Are you pasting in all old settings with the change

opaque seal Feb 15, 2018, 10:47 PM

#

I'm familiar with SQL coding (been running gmod servers for years) and added my own stuff to them over time. But with those setups, it's still very local, a server only runs so many dedi's, and they run 24/7 and available through a server browser. It's been a while since I've written anything heavy in PHP though. Where in this instance I want to have it more like, when you start a session/join a lobby, the backend(cloud) creates the dedi instance to which the clients are told to connect. Probably very much like Fortnite. Keeps players from running the servers.

It would allow persistance too without players being able to crack locally stored information on which they can then host a game.

thin stratus Feb 15, 2018, 10:48 PM

That's what gamelift does for you

opaque seal Feb 15, 2018, 10:48 PM

thin stratus Feb 15, 2018, 10:49 PM

If you want that to code that yourself you'd need a service that can launch new servers on demand and talk with the person who requested that etc

The net stuff of vs in c# is quite a thing

worthy wasp Feb 15, 2018, 10:50 PM

but when i FindSessions from the remote client - it no longer has entries

#

i debug stepped through the UpdateSession() function - everything is valid & good 😦

thin stratus Feb 15, 2018, 10:50 PM

#

@worthy wasp no idea here, sorry. As said i didn't have problems. No idea what's going wrong

worthy wasp Feb 15, 2018, 10:51 PM

all good

livid ruin Feb 15, 2018, 10:51 PM

@thin stratus this is our current system

Are you traveling maps at the same time as updating the session?

worthy wasp Feb 15, 2018, 10:51 PM

no ph33x

#

staying in same lobby UI with some updates due to the boolean return from UpdateSession()

@livid ruin And?

#

What environment?

wow, gamelift looks sick on paper, I just want to give them money even if I dont use it.

thin stratus Feb 15, 2018, 10:52 PM

@opaque seal It works quite well

#

I combined it with gamesparks

#

Gamesparks does the matchmaking and asks gamelift via http request for a server

#

Etc.

#

But yeah. Money

livid ruin Feb 15, 2018, 10:53 PM

#

@thin stratus We can launch our game, and hit "host" and it will create a new game. Then on a separate client on the same computer we hit join and it will join into the same instance. But, if I hit "host" then my friend on another computer hits "join" with the same IP inputted into our target on the shortcut. It will not connect us.

dull jasper Feb 15, 2018, 10:53 PM

#

@livid ruin one starts the game as listen, and the other opens the IP

#

kinda have to go afk now tho sry

thin stratus Feb 15, 2018, 10:54 PM

#

@livid ruin you show code of session joining

#

And then talk about ip adresses

dull jasper Feb 15, 2018, 10:55 PM

#

if u do a dev build u can join over console

thin stratus Feb 15, 2018, 10:55 PM

#

So what are you using?

untold sun Feb 15, 2018, 10:55 PM

#

Hey cedric im in the project with advection

#

we're currently using a blueprint

#

Multiplayer functionality works fine in our game, we just cant do it over a network. Currently we just have a system where we take the executable and run it through an ip like so: "game.exe 192.168.x.y IP"

thin stratus Feb 15, 2018, 10:57 PM

#

Well let me just give you some info as most people here can help you anyway

#

Same computer:

Session Joining
IP Joining 127.0.0.1

#

Same LAN:

Session Joining
IP Joining 192.168....

#

Internet:

Session Joining only via Subsystem like steam cause of missing masterserver
IP Joining via public IP

#

For ip joining you need port 7777 to be opened

#

That's all info I can give right now. Gf forces me to put phone away

#

All others here can probably help you the same though!

opaque seal Feb 15, 2018, 11:02 PM

#

If you can connect on the same system with connect 127.0.0.1:7777 (assuming 7777 is port)

#

But, it won't work between 2 systems, tells me your firewall may not have picked up the new game, which I've had from time to time. Eg: On my windows server system, the firewall won't pick up the new game till I do a LAN search (Steam search does not seem to kick the firewall off) and once I allow it, it can connect either way.

livid ruin Feb 15, 2018, 11:05 PM

#

So how would you go about doing a LAN search?

opaque seal Feb 15, 2018, 11:06 PM

#

Well for me that was a find session using bLANTrue or w/e it was. But that was already in my game. It would be best to allow the port through the firewall

#

I add UDP as well cause I can't be stuffed working out which protocol was bring used.

untold sun Feb 15, 2018, 11:09 PM

are these inbount rules or outbound

livid ruin Feb 15, 2018, 11:09 PM

#

@opaque seal

opaque seal Feb 15, 2018, 11:13 PM

#

Inbound

#

Firewalls don't normally block outbound traffic by default, at least not in the scope of that we're talking about, but you can always add the port to both if you want.

untold sun Feb 15, 2018, 11:18 PM

#

Okay we forwarded out ports through the firewall. How do we connect to each other now? Our game works locally just fine, so now we need to connect multiple computers. Should we enable LAN even though we aren't in a local network? @opaque seal

opaque seal Feb 15, 2018, 11:19 PM

#

Well I thought you were on a local network.

untold sun Feb 15, 2018, 11:19 PM

#

We arent :/

livid ruin Feb 15, 2018, 11:19 PM

#

We are trying to connect over the internet

opaque seal Feb 15, 2018, 11:20 PM

#

Is there a reason you aren't using the Steam subsystem?

#

Which does all the magic connecting of clients without this manual work?

#

From here, the host will need to forward port 7777 in their router as well.

untold sun Feb 15, 2018, 11:20 PM

#

We looked into it and it seemed more complicated

opaque seal Feb 15, 2018, 11:21 PM

#

Then the client will "connect host.ip.add.ress:7777"

#

(Public IP address)

untold sun Feb 15, 2018, 11:21 PM

#

Okay that works. 7777 is forwarded in both of our routers

opaque seal Feb 15, 2018, 11:27 PM

#

Connects n shit?

untold sun Feb 15, 2018, 11:32 PM

#

Nope.. were looking into steamworks now

dull tapir Feb 16, 2018, 12:15 AM

#

having a bit of a weird issue myself, maybe someone can help. Got one PC hosting a session in LAN and another PC joining session. It finds the session alright and joins alright, but then it just gets stuck. It never actually connects to the server or loads the level. Reading through the logs on the host PC it never actually detects any incoming connections. The last line on the client log is just "LogNet: Game client on port 7777, rate 10000"

#

if I test within the editor it works fine - this only happens when using a packaged project on 2 different PCs

i noticed when testing a new map that was all BSP that the tickrate on a listen server is identical to the server framerate
so my friends were getting insane lag until i manually capped it
is there a way to override that and set a tickrate while still having a high framerate?

opaque seal Feb 16, 2018, 1:00 AM

Actor tick rates? https://answers.unrealengine.com/questions/301308/changing-actor-tick-interval-while-running.html

not sure its that

#

its as if a dedicated server was running with a tickrate of 400

#

ive added this to my engine ini

#

📎 unknown.png

#

would that effectively set it to 50 regardless of my framerate as the host?

opaque seal Feb 16, 2018, 1:22 AM

NetServerMaxTickRate=nn

graceful cave Feb 16, 2018, 1:24 AM

assuming im using null as the subsystem

#

couldnt get direct ip connect working with steam

opaque seal Feb 16, 2018, 1:26 AM

#

DefaultEngine.ini

#

Direct IP connect doesn't use Steam as far as I know. You use the Steam subsystem and it kind if sits on top of your Session. When you create a session while running Steam subsystem, you find your Host using the Find Sessions BP node, for example.

graceful cave Feb 16, 2018, 1:28 AM

yeah i have that set up but it didnt work

Found a solution to my problem earlier. Apparently there's another variable you need to set on the listen server to actually tell it that it's a LAN server... gotta love those non-existent checkboxes which you need to spend hours searching on Google for

No, after create session when you open level you use option listen, but if it's LAN you also need to add ?bIsLanMatch=1 - took me bloody ages to find that

is there a way to get that functionality with a server browser?

opaque seal Feb 16, 2018, 1:46 AM

yes, there are tutorials that explain that. essentially you're just getting the first available session, where instead of joining, you can add it to a list using widgets etc. And in the widget you can have a join button

hey guys, i am having trouble with linetrace not getting any collision results on listen server. works fine on dedicated and local. i am doing it in c++ with visibility flag.

#

any initial thoughts on why only listen server?

#

a side note as well. when i switch the editor dedicated flag on, the linetrace doesn't work until i reset the editor

slim holly Feb 16, 2018, 8:45 PM

#

what does the debug say

#

dedicated server has some limitations for sure, it doesn't have anything visual

#

for example, it does not know what animation pose player might have but it sees the variables that drive the poses

#

-> you cannot get socket position on dedicated server

random hazel Feb 16, 2018, 9:18 PM

#

there is no debug. i have a bulletmanager in c++. on server side gun BP it calls AddBullet if it is the server.
when i breakpoint on the LineTrace call in c++ as a dedicated server it the collision succeeds and everything works fine. when I am a listen server, it goes to the same path, the bullet manager tick shows there's a bullet being calculated, but the LineTrace always fails

#

i am line tracing the ECC_Visibility channel and testing against static meshes

You trying to do it in blueprints or code?

If you're using blueprints, you should follow along with this before asking where to begin https://docs.unrealengine.com/latest/INT/Videos/PLZlv_N0_O1gYqSlbGQVKsRg6fpxWndZqZ/abmzWUWxy1U/index.html

01 - Project Overview

In this video we take a look at the finished project and step through each of the features that will be covered in this series. We show our functional Main Menu and its options, a lobby where players can chat with one another and select their characters for the game, some server options such as changing the map or match time as well as the ability to kick players from the lobby, all of this working with Steam integration. So if you are wondering how to build a networked game through Blueprints with Steam, this is the series for you!

Hey does anyone know how to know when a player finishes a seamless load? on the client side. I was trying with APlayerController::PostSeamlessTravel, but it's server side only. 😦

Hi, I'm trying to make an MMO game and I need help with a thing. In a MMO game that has a Lobby, what is the correct way to manage the connections? using UE dedicated server or websockets? (for chat, friend list, users in lobby, buy items in the shop, add friends and of course interact with a database). I found an answer in this post: https://answers.unrealengine.com/questions/738404/chat-system-shouldnt-chat-system-have-a-dedicated.html, but I don't know if It's correct.

thin stratus Feb 17, 2018, 9:46 AM

#

@solar flower @fossil spoke Can we not pin this?

#

It's really bad

#

Nothing against them creating a Tutorial. I'm happy they did. But it's FULL of errors and mistakes.
They simply teach a lot of wrong knowledge.

#

https://forums.unrealengine.com/unreal-engine/feedback-for-epic/documentation-feedback/102360-blueprint-multiplayer-video-series-is-teaching-a-lot-of-wrong-things

#

They rather read my compendium to get a good grasp of the basics and THEN watch the tutorial to hopefully spot all the mistakes and correct them while working on it.

#

@stray harbor That does sound like the way though

#

You can check the API of AActor, APlayerController or GameMode etc. and see if something sticks out

#

@abxyxx#1337 Not 100% sure but there was a MovementComponent blog post

#

Lemme check if that was client auth

#

Probably just normal authoritive networking

#

https://wiki.unrealengine.com/Authoritative_Networked_Character_Movement

Authoritative Networked Character Movement

#

But maybe it helps as a start

#

There should also be some variables for the ini files that let you specify how much of an offset the client is allowed to have before the server corrects stuff

#

@twin juniper You might want to use different connection layers for the different options.

#

A Chat, if it's only that in that lobby, can be with RPCs

#

Friends, Friendlist etc. needs to be connected to your Database

#

So that is Client (Programm) -> Database

#

Outside chatting to friends would ran over a Chat server

#

Which you could also handle your session chats with if wanted

#

Main problem you'll run into is taht UE4's servers don't support MMO class amounts of players

#

Battle Royal games with 100 players already make UE4 look "not so good"

#

They stripped down so much data, that sometimes doors don't open properly cause they don't replicate it with a high priority

#

If you implement your own movement and collision stuff, that is more lightweight than the character movement component, then you could maybe have more players

stray harbor Feb 17, 2018, 10:07 AM

#

@thin stratus Yeah there's actually a GameSession version of that call which is what I would have ended up using if we were using Game Sessions 😃 I actually ended up overloading AGameMode::HandleSeamlessTravelPlayer and just made it always recreate the player controller, which solved the original issue I was having (Basically trying to seamless travel, but don't actually want to keep playercontroller state)

thin stratus Feb 17, 2018, 10:09 AM

#

Isn't GameSession class also only Server side?

stray harbor Feb 17, 2018, 10:09 AM

#

Mmmm maybe, I'm not sure, we stubbed it out and don't use it at all

#

Anything with Session in the name I've found to be pretty bad

#

Tons of state duplication. Like I just rewrote our LAN 'session' beacon stuff, everything's been so much smoother

#

Like: The host gets a server query, just send the number of players from the GameState back.

#

No need to jump through a dozen hoops setting up an FNamedOnlineSession and all of that in our case

thin stratus Feb 17, 2018, 10:14 AM

#

Well, I'm pretty sure that Clients don't have access to AGameSession

#

So well, I think in general Epic didn't add much for Clients to know when something happens.

#

Despite BeginPlay maybe

#

And that's sometimes too early

#

OnPossessed -> ClientRPC

#

Is kinda similar to your problem

#

Also, isn't OnSwapPlayerControllers a bit early for an RPC?

#

Or is that already allowed to RPC on the new Controller?

#

I know that I'm not allowed to spawn and possess at that stage

stray harbor Feb 17, 2018, 10:16 AM

#

Possibly... we'll see heh

#

I'm off, thanks for the networking guide cedric! I started this job like 6 months ago with basically no unreal experience and now people come to me because "I seem to know the most about unreal" largely thanks to stuff like your guide \o/

thin stratus Feb 17, 2018, 10:22 AM

#

@stray harbor (: No biggie. Glad it helps!

twin juniper Feb 17, 2018, 10:27 AM

@thin stratus My idea is after login into the server, the player is sent to the main menu, this main menu has a chat and a window with the players list
connected to the server (maybe separated with channels), also main menu has a shop where the user can buy items, and a room list.

In that rooms is where the gameplay is (the map, gamemode, players characters, etc).

I'm confussed because I think I should use a different connection for the main menu and for keeping the chat in every part of the game (including when playing), maybe Websockets or similar, and the Unreal dedicated server only for these rooms.

I think each room can handle 12 max players amount, but I don't know the max rooms allowed for each server.

(Sorry for the bad english)

thin stratus Feb 17, 2018, 10:29 AM

#

Well yes, you need to have a second layer of connection

#

Number 1. handles your game session. PlayerLocation, etc.
Number2. handles everything outside a session. So Friends, Chat, Login, Shop, etc.

#

Game Session is what you call Room

#

UE4's Dedicated Servers can be the Rooms with a Game Session

#

However they don't support THAT many players.

#

So if you want something like Orgrimmar in WoW where multiple hundred players stand around, you might want to use something else for the rooms and replication

#

Like RakNet or so

#

In general, Dedicated Servers aren't really meant for MMOs anyway

#

UE4 is a Shooter engine that builds up on old classics like Unreal Tournament

#

So 16 vs 16

#

And when the game is over you'll leave and search a new server (well or stay and play another round)

#

For Number 2, the chat and stuff, you don't really want to look at UE4

#

But rather at what services, databases, etc. you want to integrate

#

Cause with c++, ue4 can basically make use of everything that has a c++ SDK

twin juniper Feb 17, 2018, 10:35 AM

#

then there is no problem if each room (session game) handles a max of 12 players? I only want 12 or 16 players for each room, It's a shooter with gamemodes like DM or TDM

#

Is not it a problem if I have 100 of those rooms, for example?

slim holly Feb 17, 2018, 10:44 AM

#

that's a lot of data tho

#

100 rooms * 12 players * bytes every player transfers back AND forth

#

vector3 is... 12 bytes iirc

#

oh and then you multiply all of it with updaterate

#

which is usually minimum of 30 for shooter game

thin stratus Feb 17, 2018, 10:54 AM

#

well each server could hold 12 players, yes

twin juniper Feb 17, 2018, 10:55 AM

#

So, would it be to have more than one dedicated server per region? p2p?

thin stratus Feb 17, 2018, 10:55 AM

#

One per 12 players

#

:P

#

You for 120 players you need to host 10 servers

#

Depending on your game, that would need 1-2 physical servers

#

If not more

#

For 1200 players you are at 100 servers

#

So 10-20 physical serverse

#

It gets expensive fast

#

So you might want to look into a more lightweight system

#

like smartfox or raknet i guess

twin juniper Feb 17, 2018, 10:58 AM

#

Ok, thanks!

is replicating in Pawn blueprint same as in Character?

jolly siren Feb 17, 2018, 2:01 PM

#

Any one know of a good way to smooth out network spikes in character movement for yourself? When I get network spikes the movement jerks you to a new position. I'm talking about the local player, not other players.

winged badger Feb 17, 2018, 2:02 PM

#

you sure its the network?

bitter oriole Feb 17, 2018, 2:02 PM

#

Rollback/Replay

jolly siren Feb 17, 2018, 2:02 PM

#

yes, I'm sure it's the network

#

Only really happens for me on my US west coast server (I'm located in eastern US and I get more frequent network spikes to west servers)

winged badger Feb 17, 2018, 2:06 PM

#

the only way i can think of server can jerk the client to a new position is if it doesn't receive the input

#

it pulls you "back"?

jolly siren Feb 17, 2018, 2:07 PM

#

No, the client misses some position updates and it gives a jerky/teleport feel

#

It's fairly rare, but the network spikes do happen like 5-10 times per match

winged badger Feb 17, 2018, 2:09 PM

#

this might be the service provider's fault

#

it jerks only the owning client? other players appear smooth?

jolly siren Feb 17, 2018, 2:11 PM

#

It's more noticeable with the owning client at least

winged badger Feb 17, 2018, 2:11 PM

#

when you provide the input owning client simulates it locally, and forwards the input to server

jolly siren Feb 17, 2018, 2:12 PM

#

I've been waiting for 4.19 to see if it helps at all since it fixes various networking bugs I've been waiting on

winged badger Feb 17, 2018, 2:12 PM

#

server then "corrects" the clients positions based on what it got

#

if you have another way that doesn't use unreal to test how stable your network connection is to the west coast server

#

i'd go for it

#

since you might lose a week trying to fix this only to realize there is nothing you could had done

jolly siren Feb 17, 2018, 2:15 PM

#

right, yeah I'm going to document the exact symptoms a bit better and also see if 4.19 helps. Then I'll profile the network more.

winged badger Feb 17, 2018, 2:17 PM

#

but if nothing except player movement is affected

#

odds are the server doesn't get all the input data

#

and it would be felt more for locally controller characters

bitter oriole Feb 17, 2018, 2:21 PM

#

If you're already doing rollback & replay, you might want a smooth interpolation rather than a reset

On client side I am calling SetActorRotation(...). Why it work on 50% ? Sometimes it works sometimes not

jolly siren Feb 17, 2018, 5:13 PM

#

Server is correcting it before you can see it? Need more info, what are you calling SetActorRotation on?

gleaming bobcat Feb 17, 2018, 5:20 PM

#

one sec please

#

SetActorRotation on Actor

#

ACharacter

#

he is not using controller roation

#

jolly siren Feb 17, 2018, 5:24 PM

#

So why aren't you rotating it on the server?

gleaming bobcat Feb 17, 2018, 5:24 PM

#

On server side the rotation is correct on owning player not

jolly siren Feb 17, 2018, 5:24 PM

#

ah

gleaming bobcat Feb 17, 2018, 5:24 PM

#

It does not help me

#

Owning player is still not rotated only sometimes

#

If set SetActor player on client side and then call RPC (server) and on server side A call SetActorRotation() replication works to all other clients but not on Owning player client

gleaming bobcat Feb 17, 2018, 6:22 PM

#

Really don't know

#

I created new template top down. Just calling SetActorRotation in player controller on Character and you have 50% chance it will happen

twin juniper Feb 17, 2018, 8:04 PM

#

Is it just me or is the UT weapon codebase extremely difficult to follow? From button press to weapon firing a bullet there are about a million lines of code

#

It seems as though instead of having a master weapon class for each kind of weapon like shootergame does (instant / projectile), they have one gigantic master weapon class that can do instant, cone and projectile fires

#

but it's all squeezed into the same class with loads of checks everywhere. I guess this is what a pro multiplayer game actually looks like!

cloud ledge Feb 17, 2018, 8:13 PM

#

@twin juniper it's the same problem that plagues charactermovementcomponent

slim holly Feb 17, 2018, 8:21 PM

#

different projectile types require different type of replication in order to save bandwidth

#

and ofc, to actually function properly

#

for example, flak cannon: it's cheaper to send the RPC with seed number byte or int for the projectile pattern, than sending transform for each pellet

#

but that doesn't work with assault rifles

gleaming bobcat Feb 17, 2018, 8:38 PM

#

Anybody experienced with SetActorRotation ?

twin juniper Feb 17, 2018, 8:44 PM

#

@slim holly exactly which makes even more complexity since they have all of the base logic in one huge master file

gleaming bobcat Feb 17, 2018, 8:44 PM

#

Nobody ...

slim holly Feb 17, 2018, 8:44 PM

#

what about rotation

gleaming bobcat Feb 17, 2018, 8:45 PM

#

How I can spend so many hours on something so trivial 😦

slim holly Feb 17, 2018, 8:45 PM

#

I assume the script size is merely to reduce input lag

gleaming bobcat Feb 17, 2018, 8:45 PM

#

let' say

#

you will create C++ topdown template

#

then you will override OnSetDestinationPressed by this

#

📎 unknown.png

#

📎 unknown.png

#

📎 unknown.png

#

and this works for other clients but you have 50% chance it works on Role == AutonomousProxy

twin juniper Feb 17, 2018, 8:48 PM

#

@slim holly is that replying to me? Fewer very large classes has less input lag than more smaller classes??

#

All of the weaps have their own child cpp class for very specific stuff and then child bps from that

slim holly Feb 17, 2018, 8:50 PM

#

or it could be internal working method, who knows

gleaming bobcat Feb 17, 2018, 10:23 PM

#

I am looking for anybody who have experience with SetActorRotation in multiplayer. I am going to pay a money for proper solution 😃

winged badger Feb 17, 2018, 10:31 PM

#

what did you mean by it has 50% chance of working?

#

what happens when it does and doesn't work, and did you guesstimate the 50%, or does it fail exacly every 2nd time

gleaming bobcat Feb 17, 2018, 10:36 PM

#

It's very random based 😦

#

Look what I want to achive is : Set rotation straight on client side. Because player in this case should not be affected by latency

#

then you will send RPC to server : "Hey I m going to set rotation to something" and the server will let other clients about my rotation change

and obv, location or rotation

#

it really doesn't matter, you would do it the same way

winged badger Feb 17, 2018, 10:48 PM

and what happens when it fails?

gleaming bobcat Feb 17, 2018, 10:49 PM

#

@ Zlo wht you mean ?

winged badger Feb 17, 2018, 10:49 PM

#

i mean server sees your clients pawn looking straight up or w/e

#

what does the owning client see?

gleaming bobcat Feb 17, 2018, 10:49 PM

#

The thing is

thin stratus Feb 17, 2018, 10:50 PM

#

It would help everyone if you'd just list what should happen and what does happen.
And that for Owning Client, Server and Other Clients.

#

Then people can way better understand what is "Doesn't work"

gleaming bobcat Feb 17, 2018, 10:51 PM

📎 unknown.png

winged badger Feb 17, 2018, 10:51 PM

you pasted the code above

thin stratus Feb 17, 2018, 10:51 PM

Yes you are setting Rotation on Server and Local Client

#

We got that

gleaming bobcat Feb 17, 2018, 10:51 PM

#

ah sorry then

thin stratus Feb 17, 2018, 10:51 PM

#

What does happen

#

Exactly

#

Best with screens

gleaming bobcat Feb 17, 2018, 10:51 PM

#

On all other clients it works on 100%

thin stratus Feb 17, 2018, 10:52 PM

#

You are currently doing this:

"My light in my room doesn't turn on. I'm using the light switch. Sometimes it works, sometimes not."

gleaming bobcat Feb 17, 2018, 10:52 PM

#

but the Autonomous_Proxy works on 50%

thin stratus Feb 17, 2018, 10:52 PM

#

Now tell me why my light doesn't work.

#

Also you are repeating yourself. We already understood that something doesn't work all the time

#

you need to present information :D

gleaming bobcat Feb 17, 2018, 10:53 PM

#

What you mean

#

If you create a top down template in C++

thin stratus Feb 17, 2018, 10:53 PM

#

We got that already

#

Don't repeat yourself again

#

I want to know WHAT exactly happens

#

Does it turn to 85°

#

Does it make a back flip

gleaming bobcat Feb 17, 2018, 10:54 PM

#

I did not tell you ?

thin stratus Feb 17, 2018, 10:54 PM

#

You say, it works 50% of the time on the local client.
But not what exactly happens if it doesn't work

#

Does the character not turn at all?

gleaming bobcat Feb 17, 2018, 10:54 PM

#

the character on Role == AutonomosProxy is rotated on 50%

thin stratus Feb 17, 2018, 10:54 PM

#

Does he lag? Does he get stuck in rotation?

#

Is the value off?

gleaming bobcat Feb 17, 2018, 10:55 PM

#

Sometimes it's works sometimes not

thin stratus Feb 17, 2018, 10:55 PM

#

I give up

gleaming bobcat Feb 17, 2018, 10:56 PM

#

sometimes is rotated sometimes not at all

thin stratus Feb 17, 2018, 10:56 PM

#

Ah, "not at all" is already more information than before

#

Now show people what how your character is setup.
Maybe share some screenshots or gifs.
Non of us has the topdown template installed and most people also won't do that to debug your issue

winged badger Feb 17, 2018, 10:57 PM

#

for example: When that code runs, everyone should see your character facing up. Server and other clients see your character facing up, while owning client sees it,,, ?

thin stratus Feb 17, 2018, 10:57 PM

#

I'm simply trying to get more information out of you

#

Cause right now, no one here knows why it doesn't work

gleaming bobcat Feb 17, 2018, 10:57 PM

#

Ok so

#

this is my setup aboput replication :

I don;t know what else I need to say

to don't repeat my words

winged badger Feb 17, 2018, 11:01 PM

#

how do you know its failing?

thin stratus Feb 17, 2018, 11:01 PM

#

What about the character movement component

#

How is that setup

gleaming bobcat Feb 17, 2018, 11:02 PM

#

I have a custom movement component

thin stratus Feb 17, 2018, 11:02 PM

#

Replication looks fine

gleaming bobcat Feb 17, 2018, 11:02 PM

#

but in this case is not relevant

thin stratus Feb 17, 2018, 11:02 PM

#

So it also fails if you use the native one

gleaming bobcat Feb 17, 2018, 11:02 PM

#

as it not working in template example

#

yea

thin stratus Feb 17, 2018, 11:03 PM

#

Don't have the template at hand, how are the settings in that

gleaming bobcat Feb 17, 2018, 11:03 PM

what setting you mean ?

of custom movement component ?

thin stratus Feb 17, 2018, 11:04 PM

and if that part was the problem, someone would already have pointed it out

so, move on from code

#

and try to explain what is happening as if we never coded a line in our lives

thin stratus Feb 17, 2018, 11:08 PM

#

I also don't know why you post the code when i ask for movement comp settings

#

Something is setup wrong, cause i can set rotation just fine

gleaming bobcat Feb 17, 2018, 11:08 PM

#

In this case it's c++ top down template with no modification

#

The other clients works fine

#

but Autonomous_Proxy is rotated correctlu on 50%

pallid mesa Feb 17, 2018, 11:09 PM

SimpleMoveToLocation is not meant to be used on a networked environment

Just from the code above (what you can simply reproduce) what is wrong ?

WTF the server correclty replicate the rotation to other clients

winged badger Feb 17, 2018, 11:16 PM

#

and you can tell that because?

gleaming bobcat Feb 17, 2018, 11:17 PM

#

but Role == Autonomous_Proxy is rotated on 50%

#

which menas

#

sometimes is rotated sometimes not

winged badger Feb 17, 2018, 11:18 PM

#

under which conditions is it rotated and under which its not?

gleaming bobcat Feb 17, 2018, 11:18 PM

#

I told you everything what I am doing

winged badger Feb 17, 2018, 11:19 PM

i am at this point interested only in what you see on screen

gleaming bobcat Feb 17, 2018, 11:19 PM

#

From my point of view

winged badger Feb 17, 2018, 11:19 PM

#

because you pasted a piece of code that should work

#

and told us pretty much "something about rotation bugs out randomly"

gleaming bobcat Feb 17, 2018, 11:19 PM

#

It looks like : Im setting the rotation on Role -- AutonomousProxy

#

then I am calling RPC to server (hey I want the rotation fo me to something) and the server will replicate my new rotation to all other clients

#

but the server override my rotatation before my RPC will come

#

As I said it's very easy to reproduce with steps what I provided early

#

Just tell me a solution and I will pay you a money straight a way

#

Just stop talking about that on theory side just make a project and try it

pallid mesa Feb 18, 2018, 12:48 AM

#

Just fyi I downloaded the top down because I was so curious about why that wouldn't work, and yep, the rotation replicates correctly but doesnt update properly on the local client. However, It does after a couple clicks. Didn't check further and I don't know if I will, the guy left the discord and it seems to be something project specific ~

winged badger Feb 18, 2018, 12:53 AM

@twin sorrel what I did, was make 2 actors one for fps gun, other for tps gun. Then I have it spawn with run on server, and multicast events. What I do to make them visible/invisible was setting the owner of each gun, then putting "set owner only see" nodes

using a listen server (vs. e.g. a dedicated server) for a game like Journey with cooperative multiplayer should be fine, right?
also NAT punch through shouldn't be a problem when using steam works, right?
(using journey only as an example for a serene, not necessarily super exact multiplayer experience)

Question: I have functionality attached to my master character BP that says, when in range and when looking at object, display object name

When server owner looks at item, everything is fine

When player client looks at item, it also shows the item name to the server player. And regardless of distance

#

📎 unknown.png

#

those two things, I don't want to happen. Any help would be appreciated

winged badger Feb 18, 2018, 8:38 PM

#

you need to send a client RPC for setting Hidden

#

and that will only work if you're doing it from a PlayerController, or an object attached to it

#

basically

#

EventTick executes on both client and server

#

so everything you just pasted executes on both client and server version of the object

#

you can't do SwitchHasAuthority, because it would disable the exec for either clients or server completely

#

you can, alternatively, do (if you can get relevant Pawn from there), put a branch to see if the Pawn is locally controlled

#multiplayer

works as a key. in-editor ya.
